rr not recording getpriority() (Failing to record firefox-23 on x86: "recorder: unknown syscall 96 -- bailing out")

This is with today's nightly i686 build, running in an x86 VM on an x86-64 system. Lots of moving parts here, not sure yet where the problem is. Full output below.

Hi Chris,
system call number 96 is unimplemented.
